AMEDEO .A. MANCINI, OF BROOKLYN, NEW YORK.

TIME-LOCK.

To all "whom it may concern jBeit'known that I, AMEDEO A. MANOINI,

a subject of the King of Italy, residing at the borough of. Brooklyn, inthe city of New York, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Time-Locks, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, which form a part thereof. 7 My invention relatesto time locks,- and more iarticu larly to a type thereof wherein a clockworks controls the bolt actuating mechanism, the lock of my inventionbeing adapted for use alone or in connection with the ordinarypermutation lock.

In a lock made in accordance with my invention, the locking means forthe bolt actrating mechanism is so constructed that it has normaltendency to engage and lock said mechanism immediately that the boltsare shot, and wiil be automatically retracted to permit the actuation ofsaid mechanism at predetermined intervals as. determined b controlled bythe clock works. The releasing mechanism itself may be so set as toinsure its action upon the locking member at different desired intervals. Furthermore this releasing mechanism, in withdrawingthe lockingmember, is

a source of power independent of the clock works, so that in the eventof the disarrangcment of the clock works as a result o external shocksupon the door carrying the locle it continued rapid movement of theclock works and the releasing mechanism should result, the speedattained by said releasing mechanism will be sufficiently high to avoidwithdrawal of-the locking 'memher for a siniicien-t interval to perunitthe actuation of the bolt mechanism. If continuous pressure he appliedto the knob spindle so as to withdraw the bolt during the brief intervalwhen the releasing mechanism is operative under the conditions abovereferred to, this pressure under ordinary'con- 'ditions will deveiopsuch friction between said locking member and the support therefor, andbetween said actuating means and said locking member, to: preventmovement of the releasing mechanism to effect the release of saidlocking member lVhile, when the actuating mechanism has been actuated towithdraw the bolts, the con Specification of Letters Patent.

Patented July 20, 1920.

Application filed October 7, 1919. Serial No. 329,127.

dition will be such as to prevent the locking member becoming operativeas to this mechanism until the bolts are again shot, I providesupplemental means operative upon said locking member which may be soset as to maintain said member inoperative as to the actuating means,thus permitting the instantaneous locking of the door at any time by themere turning of the knob, which is desirable in the case of anemergency, or preventing the accidental locking of the door through thetime lock mechanism.

The locking member is so constructed and supported as to withstand anyforcing stresses applied to it through the actuating mechanism, andprevents such stresses being transmitted to other mechanisms of thelock.

ile a single clock works mechanism and a single releasing mechanism maybe em ployed, it is possible, and sometimes preferable, to duplicatesuch mechanisms and have them act simultaneously upon the actuatingmechanism locking member, so that in the event of the failure of oneclock works to properly function, the other will nevertheless continueto act. It is also possible to so set the releasing mechanism associatedwith the different clock works, to insure their successive actuation,thusproviding a predetermined interval so that the locking member willbe actuated twice during a brief lapse of time, thus permitting theopening of a door after a short predetermined interval in the event thatthe dooris not opened when the first releasing me -hanism operates uponthe locking member, or is due to operate thereon in. the event that itfails to so operate.

The invention consists inthe novel features of construction andcombination of parts hereinafter set forth and described, and moreparticularly pointed out in the claims hereto appended.

Referring to the drawings, Figure 1 is a vertical section through thecasing of the time lock mechanism, disclosing the various mechanisms inelevation;

Fig. l2 is a view of the invention in a form employing single clockworks and a single releasing mechanism actuated thereby. Like lettersrefer to like parts throughout the several views; 7 In the form of theinvention shown in the go drawings, the time lock mechanism is mount-;ed in a casing A'adapted to be mounted upon il ClOOl' in any desiredmanner, said casing being closed bymeans'of the plate A, having openingstherein through which portions ofthe bolt actuating mechanism maybeobserved when the door is open. Mounted 'within the casing A is a boltactuating mechanism consisting of a plate a havin'g pivoted thereon,adjacentthe periphery thereof, a plurality of links a", a? andm, each ofwhich links is pivotally connected to. a bolt structure as a shown'indetail in Fig. & of the drawings. The detailed constrnction of this beltstructure is immaterial to this invention, .as any desired number andarrangement of bolts may be employed. The plate a; is carried by androtatable with a spindle I) which projects through the casing and thedoor carrying the casing, and is equipped with the usual handle or knob71'. Said plate a is so constructed as to have a limited turningmovement in one direction to withdraw the bolts, and a return move mentto the same extent to project the bolts, the time controlled lockmechanism being operative upon this plate to prevent movement thereofduring that interval when it is desired to prevent the actuation of saidplate and the bolts controlled thereby. j

The means limiting the movement of said plate a to that required toretract or to shoot the bolts, consists of a heavy rod 6 carried by thecasing A and its closure'platevA', and projecting through a segmentalopening ('31 in the'platea. One end of said'opening c is enlarged as atc to receive the locking member operative upon the plate a, this en,-largement being at the end of saidslot which is adjacent the rod 0 whenthe bolts are shot. V

Slidablymounted upon the rod-0' is a locking member d, the diameter ofwhich is sufficiently'greatnot to enter the segmental slot 0', butsufliciently small to freely enter the enlargement 0 of said slot.Actingupon the member .65, with a normal tendency to force it toward theplate a, is a spring cl. -The member-d is provided with a lug (Z securedto which'is a stem d 'p roj ecting through the closure A and providedwith an actuating the )inv (Z out ofre 'ister with the evenin '(Zfltoprevent the spring d acting upon the 'member -(Z, and thus avoid thepremature locking of the member a 1n the eventof the accidental shootingof the bolt-during that time when it is desired not to l'ock the doccarrying the lock mechanism.

Cooperating with the locking member (1 is a releasing mechanism orreleasing mechanisms controlled by suitable clock works so that saidmember will be automatically 'withdawn from its operative relation tolock the plate a at'predetermined intervals.

In Fi 1, 2 and 5' I have illustrated a lock employing two releasingmechanisms of this character; while 111 Flg. 12 I have illustrated aleck employing but one such'mechanisin. hen but'asingle releasmgmechamsm1s used, as shown in Fig. 12, theconstruction will be the same as when aplurality of re- A deleasing'mechanisms are employed.

tailed description of but one of these mechanisms will therefore begiven, and the same reference letters will be applied to the differentreleasing mechanisms shown in the drawings.

The releaslng mechanism above referred to compr1sesagear wheel 6 havingmounted its thereon one or a=plurality of memberse adapted to coiiperatewith an abutment 0 carried by the locking member (Z, said member e andabutment 6 being so constructed as to develop a wedging action as, theformer passes the latter, such as to impart rectilineal movement to themember d sufiicient to disengage it from the plate a. In the form of themventlon shown this effect is secured by forming the members a with aninclined portion 6 terminating in a short flat portion parallel with theface of the gear a of sufficient length to hold the member d retractedfor a suflicient interval to permit the rotation of 'the'plate Themember a is carried by a sleeve 6* mounted upon the-shaft f, which isjournaled in suitable hearings in the casing A and plate A. Carried bysaid shaft f is a spring drum f, the freeend of the spring of which issecured to the geare. Carried by the shaft f is a ratchet wheel 7cooperating with which is a pawl F. The shaft .7 is provided with aknurled head 7 by means of which the spring of the drum f may betensioned, the ratchet mechanism described holding said shaft againstreturn movement under the tension of said spring.

The spring of the drum f has a normal tendency to rotate the wheel 6 ina manner to engage the member 6 carried thereby with the cooperatingabutment 6 carried by the member (Z, this tendency being restrained by agear train connecting the member 0 with a clock works 9, so that thesaid spring drum can operate on the member 6 only at certainpredetermined intervals.

The gear train above referred tov comprises the gears hand i mountedupon a shaft j journaled in the casing A and closure plate A, one end ofwhich projects through said closure plate and is provided with a diallinger j adapted to indicate upon the graduated dial j how the mechanismis set to operate. The gear-it is in constant mesh with the gear 6. Thegear 2' is an interrupted or mutilated gear, the portion thereof devoidof teeth permitting the free running ofv the geare at the time set forpermitting the artuation of the plate a to withdraw the bolts. The gear2' is inmesh with a setting gear. carried by a sleeve-7c, the end ofwhich is provided with an actuating head 72 externally of the closureplate A. The sleeve 70 is rotatably mounted upon a shaft m carrying thelast gear m" of the train which meshes with a gear of the clock works 9.

The sleeve 76' is adapted to be disconnected from the shaft m to permitthe setting of the lock through the gear 70, or to be connectedtherewith to operatively connect the gear 6 with the clock works 9, bymeans of a lock nut m carried by said shaft m, and adapted tofrictionally engage the head 70 carried by the sleeve 70'. By thisconstruction the lock may be set independently of the clock works.

The spring of the clock worksmay be ensioned by means of an ordinary keystem g Vhen two releasing mechanisms are employed, the locking member (Zis provided with two abutments c as shown, while, when but one releasingmechanism is used, only one such abutment is provided.

The gear 0 carries a plurality of indicators a exposed through anopening in the closure plate A, said indicators bearing't-he days of theweek, or othermatter indicating to the user of the lock, conditionsabout the mechanism. a

When using a plurality ofmembers .0, they may be so set as to releasethelocking member (Z after similar or dissimilar inter- Vale of time, theadjustment of these mem bers beingpossible by providing the side of thegear 6 with spaced screw threaded openings, as shown in Fig. 2 of thedrawings.

the setting gear, however,

The operation of the herein described lock is substantially as followsTime locks made in accordance with my invention may be made to astandard design, and any desired variance in the intervals at whichthereleasing mechanism is to become operative to. disengage the lockmember (Z from the plate a, secured by different adjustments in thereleasing mechanism, or particularly where long intervals of time are toelapse between the actuation of the releasing mechanism, the lock may bespecially designed.

Referring more particularly to the form of the invention shown in Figs.1, 2 and 5 of the drawings, where two clock works, two releasingmechanisms and a plurality of members 6 upon the gear 0 are used, saidmembers 6 will be so spaced apart as to consecutively reach theoperative relation to the abutment c cooperating there-with, atintervals of twenty-four hours, providing it is desired to open the safeat such intervals. TV hen access may be had to the knob 70 of thisinterval may be arbitrarily varied so that a person may vary .the timeat which the clock'may be actuated, from day to day, if it be sodesired. Furthermore, if it be desired to prevent the actuation of thelock for a period of more than twenty-four hours, this result may besecured by omitting that member 6 which normally would be operative uponthe day when it is desired to prevent the lock mechanism being actuated.It would follow, therefore, that the members 0 may be so ar ranged uponthe gear 6 as to secure such an actuation of the look as would permitthe bolts to be withdrawn at varying intervals at the will of the userthrough the sequential arrangement of said members 6.

lVhensetting the device, the lock nut m is released and the sleeve 70 isrotated by means of its knob 71: the loosening of the nut mdisconnecting said sleeve and. its gear it from the gear m and the clockworks.

Assuming that'the parts are .inthe position shown in Figs. 1 and 2, witha .vedge member 0, just about to engage its cooper-at ing abutment 0 theturning of said gear 7: in the direction of the arrow (Fig. 5) willcause. said member 0 to recede from its eoopcrating al mtment to anextent deter-mi, ed by the quantity of rotation of said gear. Each ofthe grad'uations upon the dial plate j indicates a predetenn-ined timeinterval, as one hour, so that by setting the dial finger j" at acertain number of graduations from the point at which it is shown uponFig. 5, will require a corresponding number of hours to elapse beforethe member 6 will again reach the operative relation to its abutment eAssuming that it is desired to open the safe after sixteen hours, thefinger y" will be set at the sixteenth graduation upon the dial j movingsaid finger contra clockwise;

When the releasing mechanism has been so set, the nut m is againtightened, connecting the sleeve 70 with the shaft m,thus.

again connecting the releasing mechanism sides of said slot.

1 1 After the lock has been set, the door may the full projection of thebolt mechanisms a,

. locking action of the member .th1s gear belng totally inoperative andd1sbe closed and locked at any time by a return I movement of said platea, the-locking member '(Z entering the enlarged portion 0 of said-. slotsubstantially simultaneously with It will be observed that the-gear eand its appurtenances has no function so far as the (Z is concerned,

connected from the member cl at all times excepting that at which thelock is'set to permit the actuation of the lock. Any'force appliedthrough the stem Z) to the plate a with an attempt to force the lock,will be transmitted through the member d to its heavy supporting rod 0,which possesses suflicient strength to withstanduany such l stresses.

1 the ,From the instant the lock nut m is set against the knobla", thegear e will be continuously rotated at low speed'throughthe gear trainh-i7cm, this speed being determined by the clock works 9. 'With a givenlapse of'time a member 6 will ap-' proach its cooperating abutment e andat instant for which the actuation of the releasing mechanism is-set,the last: gear tooth of thegear '5 will pass from mesh'with the gear 72,thus momentarily disconnecting the gear e from the clock works andpermitting a limited rotation of said gear 6 under the control of thespring drum f, this interval being sufficient to cause the inclined faceof the member 6' to engage and impart such movement to the member at aswill withdraw r it from engagement with the plate-0a.. The

short surface'of the member 6 beyond said incline will holdthe member atin this position for a lengthof timedetermined by the length of thisflat portion. The extent of rotative movement of the gear e'under thespring drum f is determined by the length of themutilated portion of thegear 11,- the 'first tooth of said gear beyond said mutilated portion,immediately arresting the move- 7 ment of the gear 6 under the controlof the drum f, but continuing the rotation thereof under the control ofthe .clock works. The

resistance encountered by the gear e during 6 may be used to rotate saidplate to retract the bolts. 7

As heretofore stated, after the members 6' pass out of engagement withtheir co'ciperatingabutments 6 the bolts may beshot and instantly lockedthrough the time lock mechanism, at any time, by merelyturning the platea.

i Rectilineal movement of the member 62 is assured by the use of the rodd which prevents rotationofsaid member upon the rod 0, this constructionbeing used to not'only prevent such rotation, but permit the withdrawalof the member d from its engagement withftheplate a at any time whileaccess may be had to the lock, the knob '(Z and pin (Z permitting thismember to be held in itswithdrawn position so as to prevent theaccidentallocking of the member a during the time when it is desired tohave the door remain'open,

To accurately position'the abutments 6 in theplane of movement of themember or members 6', I provide the plate a adjacent the enlargedportionc of theopening c with a stop plate d adapted to be engaged by themember (Z after it enters the enlarged'portion 0 of the slot 0. i r

' When a door is closed and locked, the plate (i cannot be turned toretra'ctthe bolts a until the next member 6 becomes operative as to themember. al. 7

By the use of two clock works and two releasing mechanisms, I secure asafeguard against the failure of one of said clock works to. properlyfunction. Furthermore, the

members 6 upon the different gears 6 may be so positioned that oneofthem will engage its abutment a short time after the other is timed toengage its abutment, so thatin the event of a failure to actuate theplate a when the first abutment disengages the member at therefrom, theuser'may nevertheless, after a short interval, retract the bolts a whenthe membere of the. other gear 6 is operative in relation to said memberd.

' :In the-event of external' shocks, idisa'rranging the-clock works,and-thus removingthe time control from the gear 6, said gear 6 will turnwith great rapidity under the control of the spring drum 7, bringing themembers 6 into rapid successive operativeengagement with the member d.This engagement, however, will: be 'only.momentary,.so thatit wouldbeextremely difiicult, if not'impose from, but adapted sible, Ito turnthe member a to retract the bolts while the member d was'disengagedtherefrom. If it should be sought to apply a continuing pressure uponthe handle 6 so ias'to take advantage of this momentary disengagementotlthe member'd, this pres sure would develop suificient frictionbetween the plate a and the member (3, and between the member (Z and itssupporting rod 0, to arrest rotative movement of the gear 6 byovercoming :the tension of the spring ot'the drum f. .As a furthersafeguard,'however, the various bolt mecha-' nisms a may be controlledbya permutation lock, although this feature is immaterial, and bears norelation to vmypresent invention, which relates merely to the mechanismpermitting'the actuation of the bolt actuatmg mechanism only atpredetermined intervals.

A time lock mechanisinmnde in accord ance with myvinvention has theadvantage of extreme simplicity of construction, which,

n a'time locl:,.is desirable.

It is not my intention to limit the invention to the precise details ofconstruction shown in the accompanying drawings, itbein g apparent thatsuch may be varied without departing tronr'the spirit and scope of theinvention.
